Proof, not promises.

Most student portfolios stop at mockups. Mine points at merged code: four pull requests accepted in September 2026 by the maintainers of Prettier, pnpm, Tabby and Undici.

At home I build for Bicol and for students like me, and I verify what I ship with regression tests, maintainer review and real deployments.

  • Use printf instead of echo for POSIX path normalization

    pnpm/pnpm · merged 15 Sept 2026 · Rust · shell · package managers

    • POSIX bin shims were corrupting Windows-style paths: echo turned \n and \t inside C:\node_modules\.bin into control characters.
    • Switched the Rust cmd-shim header to printf, added regression tests, and made warm reinstalls rewrite stale shims.

  • Do not report aborted on successful cache hits

    nodejs/undici · merged 15 Sept 2026 · Node.js · HTTP caching

    • The cache interceptor reported aborted=true on successful hits because the flag aliased stream.destroyed.

About/

My story

I’m from Bicol. I studied STEM at Bicol Regional Science High School, then came to Metro Manila for Computer Science at PUP, where I hold a 1.32 GPA, with 1.00 the top mark. I learn by building real things and reading the systems underneath them. Backend, databases and architecture pull hardest. I use AI to move faster, and tests and code review to stay honest.

Now & before

Media Partnership Lead at Seekers Guild since August 2026. Backend AI Engineering in FlyRank AI’s educational program since July 2026. Member of the Junior Blockchain Education Consortium at PUP Manila and of AWS Cloud Club PUP, October 2025 to August 2026. BS Computer Science at PUP since 2025, after a STEM diploma from Bicol Regional Science High School.

Awards

1st Runner-Up at the GDG on Campus PUP SparkFest Hackathon with BANTAYOG, out of 15 teams and 10 finalists, July 2026. Top 20 Finalist at the CrypTita Plays Builder Showcase at WOCEE, also with BANTAYOG.

Toolbox
